crash on close

[Elfy]

xubuntu-staging gmb

Version: 1.1.14~ds0-0ubuntu1

[Simon Steinbeiß (ochosi)]

I ran gmusicbrowser from the terminal with the -debug and -backtrace options, see output attached.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Elfy (elfy)]

unpacked files from the crash report are available, couldn't run ubuntu-bug as it's from PPA

1) Could you give me some context. Does it crash all the times, sometimes, with a specific layout, have you tried disabling all plugins (-noplugins command line option does that) ... ?

2) the -backtrace option can be useful but is limited as it only prints a backtrace when something is printed.
There is a way to get the full trace of the executed perl code, I'm not sure it's a good idea, I never tried to debug something with it, but maybe you could try :
Install libdevel-trace-perl
run perl -d:Trace /usr/bin/gmusicbrowser 2>&1 |gzip >fulltrace.gz
compressing it is important as it gets very big but compresses very well (just tried with my library, 9M compressed, ~1G not compressed !)

3) segmentation faults can be tricky to track down, as it may corrupt some memory, and then crash some time later at a random point for no apparent reason. So I don't know if a full trace will help

This crash – along with the crash that happens with 1.1.13 (https://bugs.launchpad.net/ubuntu/+source/gmusicbrowser/+bug/1401609) – happens frequently, but not always. As far as I could narrow it down, I at least need to play back a song for a minute or more to trigger the bug. Without playback gmusicbrowser usually shuts down just fine.

The crashes happen with Xubuntu's default setup, which is the Shimmer Desktop layout plus the patches Debian carries for gmusicbrowser.
I haven't tried disabling plugins yet, but that's a good idea, I'll try that next to narrow the issue down. I can also try with an empty library (although the fact that others have reported the bug as well doesn't really suggest that it's a problem of my gmbrc).

I can also try a full backtrace. Even though I'm a bit sceptical too, it might give us some clues.

[Simon Steinbeiß (ochosi)]

Oh, let me add that the shutdown crashes also happen when running gmusicbrowser from git master.

[Elfy (elfy)]

I didn't even try playing anything - just tried the app after Simon asked me too - I got a crash on quit after it'd dealt with updating library.

For me it seems to only crash when using the Shimmer Desktop layout.
